    聚(脲酯):具有高熔融温度的可生物降解的聚合物系列
    摘要:
    聚脲酯是一类聚合物,旨在弥合脂族和芳族聚酯之间的间隙,在这些间隙中,高熔融温度和生物降解性相互矛盾。这些新型的可生物降解的聚合物在较高的温度下熔融,可以通过缩合尿素,氨基醇和二甲基酯来简单地制备它们。

    synthesis of symmetrical N,N′-bis(hydroxyalkyl)ureas, OC[NH-(CH2)x-OH]2 (x = 3–6), by oxidative carbonylation of α,ω-amino alcohols [3-aminopropanol (3-AP), 4-aminobutanol (4-AB), 5-aminopentanol (5-APe), 6-aminohexanol (6-AH)] with CO/O2 mixtures (O2 = 5 mol%) in the presence of Pd(II)/ligand/NEt3·HI catalytic systems. The catalytic process takes place under very mild conditions (p(CO/O2) = 0.1 MPa; 303–333 K)

    The present invention is directed to a method for treating a material to impart wrinkle reduction and temporary crease resistance thereto, and improve feel. The method involves: applying to said material a solution of a treatment composition in an amount effective to impart temporary crease and stain resistance, said treatment composition contains a hydroxy urea or hydroxy amide compound; and allowing said treatment composition to dry at ambient temperature, wherein said hydroxy urea compound comprises one urea and at least one hydroxyl group and said hydroxy amide compound comprises at least one amide group and at least one hydroxyl group. The material treatment is useful in reducing wrinkles in clothing, improving the feel of fabrics, and increasing the moisture adsorbence and retention in natural and synthetic fabrics.

  • Method for imparting permanent press to textiles
    申请人:National Starch and Chemical Investment Holding Corporation
    公开号:EP0969138A1
    公开(公告)日:2000-01-05
    A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a (hydroxyalkyl)urea and/or a β-hydroxyalkyl amide crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The crosslinking agent is free of formaldehyde. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.
    一种使含有纤维素纤维的织物具有永久压榨性能的方法。该方法包括将(羟基烷基)脲和/或 β-羟基烷基酰胺交联剂的水溶液涂抹在纺织品上,并在足够的温度下加热纺织品足够的时间,使交联剂与纺织品发生反应,同时从纺织品中除去水分,从而赋予纺织品永久的压榨性能。交联剂不含甲醛。本发明的方法可使经其处理的纺织品具有永久压榨性能,并提高这些纺织品在今后洗涤时的耐磨性。与未经处理的纺织品相比,经过处理的纺织品褶皱明显减少。此外,经过处理的纺织品触感柔软,在洗涤后仍保持光滑。
